Support calendar_range

[brianmsm]

Hello
I have tried to make a calendar_range from the calendar function, however, I can't get it to work correctly when I add the javascript code here, which allows me to do the shading and set the boundaries on each calendar.

I leave a reproduction of my example without javascript code specific:

The problem is that when I use the specific javascript code, the table can no longer be filtered when I change the date ranges. While when I don't use that code, it can be filtered.

I fixed the maximum date problem and unresolved comments in #366 and I open a new PR #415, After reviews #366 can be closed.
